Give us more info about what exactly you have in mind. Are you just trying to break up the journey for a day or two, or considering spending a few days here and there while eventually making your way to Venice?

lol good point. Probably just breaking up the journey for a day – if there are worthwhile places. If not, I guess go straight to Venice. Just seemed like it would be a good plan to break up the trip and avoid sitting for an extended period of time.

If you’re only going to stop for a day, I’d just look for a flight from London to Venice. The other “easy” possibility would be Eurostar to Paris for a whirlwind day or two there and then the overnight train to Venice.

I didn’t even think about flying since I was stuck on the idea of the Eurail. This makes more sense. I’ll probably make Paris my last stop so that I can start from London, proceed to explore Venice, the Croatia islands, Rome, Barcelona… and loop back to Paris.
